NE556N Description

Short technical summary and product information.

The NE556N by STMicroelectronics is a dual monolithic timing circuit designed for stable time delays and oscillation. It operates in both astable and monostable modes, controlled by external resistors and capacitors. The device features a high output current capability, able to source or sink up to 200mA, and is TTL compatible.

 

Key electrical specifications include an operating voltage range of 4.5V to 16V and a maximum operating frequency of 500kHz. The temperature stability is rated at 0.005% per degree Celsius. The NE556N is designed for through-hole mounting and comes in a 14-DIP package, with an operating temperature range of 0°C to 70°C.

 

This dual timer circuit is suitable for applications requiring precise timing from microseconds to hours. Its versatility allows for accurate control of frequency and duty cycle in oscillator configurations, or precise time delays in monostable applications. The reset input overrides all other inputs, ensuring reliable initiation of timing cycles.
